  • Harvest in 16-24 weeks. Some improvement in flavour if left till after frost..
  • Compatible with (can grow in same bed): Best kept separate
  • Horseradish leaf

Horseradish is grown from root cuttings. If you know someone who has it in their garden, just one piece of root will start off for you.

Dig a deep hole and refill with compost as the horseradish has a long taproot. Plant it and then leave it alone. Apart from constant wet or cold, horseradish will grow in any part of the garden.

Horseradish is an aggressive grower and will quickly take over the garden. It will also grow well in a deep container or sink an old bucket in the ground to prevent spreading. Otherwise, remove all the plant when you harvest it and save one piece to replant.

Can be planted in early Autumn or Spring

Anyone know where I can buy a horseradish plant, either from a nursery or online. I live in the Sutherland Shire, in Sydney. Cheers.

Ferndale Nursery in Constantia, Cape Town has plenty horseradish plants for sale. Owner Errol has been growing it for many moons. Around R32 for a nice size plant.
